Those pictures are great! But only as an example. I would NEVER estimate the CYA level based on them. Cameras pick up things the eye doesn't and may be making the CYA look lower than it is.

I have outdoor speakers on my deck. No matter HOW I look at them I cannot see the woofer and tweeter through the grill. But the pictures taken CLEARLY show them... That's an example of my point. The camera is a better "eye" than the eye.
